T o. altwhom 'it may' concern: I

B e 1t known that I, FRANK KLosI'NsKI, a' sub]ect of the Czar of Russia, residing at St.

Y Louis,in the State of Missouri, have invented a new and useful Can Lock and Cover, of whlch the following is a specification.

This invention relates to`closures for milkcans and similar containing vessels'` and has for its object to provide a com aratively simple and lnexpensive device ofP this character which forms an air and liquid tight cover for the vessel s'o as to efectually prevent the contents thereof from spilling or leaking at the cover during trans ortation or shipment. A f urther ob] ect of t e invention isto provide lmproved means for 'locking the cover in engagementwith the can, and means for limexpose the contents of the vessel.

iting the'swmging movementpf the ivoted locking bail.. p

A st1ll further object of the invention is generally to lmprove this class of devices so -ast o increase their utility, durability' and vefficiency as well as to reduce the cost of manufacture.

Further ob'ects' and advantages will apear 1n the fol owing description, it being unerstood that various changes in form, proportions and minor details o f construction `may be resorted to within' the scope of the ap ended claims.

n the accompanying drawings forming a part oit' this specification: Figure 1 is aside elevation of av containin vessel provided with a combined cover an lock constructed `'in accordance with my` invention, the iv-k oted locking bail'beilg responding parts in all 'of the figures of theA drawin s.

The lmproved device forming the subject matter of the present Vinvention may be used ordina in connection with milk cans and similar vcontaining vessels and by way 'ofillustration isA shown in connection with aniilk can of the construction in which 5 designates the bo y of the can and 6 the "neck, preferably reinforced and strengthened by a ring or band 7, as shown,

vtion of the shank of a The cover 8 is provided on its lower face Patented .my 14, 190s.

with an annular groove 9 in which is seated a i gasket 10 which bearsagainst a reinforcing.

rib 11 formed on the upper` end of the neck 6 and serves to forman air and liquid tight joint between the ,can andvclosure.

' Secured to theltop of the cover 8 is a handle 12, preferably formedpfrom a metal rod, the intermediate portion of which is bowed outwardl" and the op osite ends thereof extended t rough suita le loops or clips 13 fastened to the top ofthe cover 8 to produce laterally extending lugs 14.

, Secured to the reinforcingrband 7 arelol positely disposed ears 15 the ee ends of W ch are extended vertically .above the/top of the .can' and are bifurcated to form terminal sockets 16 adapted' .to receive the locking lugs 14.

Extending laterall from the band 7 are tru'nnions 17 on whic is pivotally mounted for swinl ing movement a locking bail or yoke 18, the atter being retainediin position on the trunnions by cotter pins o similar fasteningrdevices 1'9. r

he bail or yoke -18 is provided with a cam face 20 which bears against the lugs'14 and forces thelatterwithin the socket 16 when the bail is swung downwardly to operative po- .sition thereby to clamp the Acover in engage ment with the neck of the can.

The closed end o'f the yoke 18 is` bent laterally to form a loop 21 which registers with an arm 22 secured to and` extending at right i prof vi ed with a slot v23 so as to permit the inserpad-lock or similar fasan les to the band. 7, said arm being tening device 24.

1 The opposite arms of the-locking bail or oke are spaced from the ears 15 by circular locks or washers 24', while the terminals of the arms at the trunnions 17 are provided with extensions 25 'having inclined faces. 26 which bear against the correspondingly inclined faces o? suitable lugsor enlargements 27 secured to the reinforcing band 7, thereby to limitv the swinging movement `of the lock-` he cover 48 is preferably combined with the can by a` chain or similar iiexible medium 28 so as to prevent accidental displacement of the cover Whenthe latter is moved to open position. 1- t In sealing the can the cover orclosure 8 is placed in position on the bead 11 with the ingrbail or yoke.

lugs 14 seated in the sockets 16 of the ears 15 after which the operator grasps the locking bail by the loop 21 and moves the latter to the position shown in Fig. 1 'of the drawings. As the locking bail or loop is swung to operative position on the trunnions 17 the can faces 20 will engage the lugs 14 and force said lugs within the sockets 16 thus compressing the gasket 10 and forming an air and liquid tight joint between the parts. After the bail has been moved to operative position the shank of the pad-lock is extended through the loop 21 and the slot 23 so as to eifectually prevent an unauthorized person from obtaining access to the contents of the can. y Y

In order to open the can it is merely necessary to remove the lock 24 and then swing the locking bail laterally to the position shown in Fig. 2 of the drawings thus permitting the cover to be detached. from the can by exerting an upward pull on the operating handle 12. It will thus be seen that the loop 2] not only serves as a means for engagement with the pad-lock but also forms an operating handle by means of which the bail may bc moved to operative and inoperative position. If desired, however, the lock may be dispensed with, the can face 20 being relied upon to lock the lugs 14 within the sockets of the supporting ears.

The Vimproved mechanism herein shown and described may be applied to milk cans or other containing vessels of different sizes and shapes and if desired, the reinforcing band of the can may be dispensed with and the locking bail or yoke and its associated parts attached directly to the exterior walls of the vessel. p

From the foregoing descri tion it will bc seen that there is provide an. extremely p simple, inexpensive and efficient device a mirably adapted for the attainment of the ends 1n view.

- Having thus described the invention what is claimed is:

1. The combination with a containing vessel having vertically disposed ears the free ends of which are bifurcated to form terminal sockets, of a cover extending transversely across and bearing against the top of' thereof bent laterally to form a movable locking member ada )ted to register with the slot in the arm for tire reception of a locking device, said bail being provided with a cam face adapted to engage the lugs when the bail is moved" to operative position.

2. The combination with a containing vessel having enlargements formed thereon and provided with inclined faces, of a cover extending transversely across and bearing against the top of the vessel and provided with laterally extending lugs, ears secured to the vessel at said enlargements and having their upper ends extended above the top of the vessel and bifurcated to form sockets for the reception of the lugs, a locking bail pivotally mounted on the vessel and having its pivoted ends provided with extensions formed withinclined faces adapted to en gage the inclined faces of the enlargements, said bail being provided with cam faces adapted to engage the lugs when the bail is moved to operativo position.

3. The combination with a containing vessel having a reinforcing band secured thereto, of a cover extending transversel)Y across the top of the vessel and having ils lower face provided with an annular seating groove, a gasket seated in said groove, clips secured to the upper face of the cover, a rod journaled in the clips and having its opposite ends extended beyond the peripheral edge of the cover to form lugs, the portion of the rod between the clips being bowed laterally to form an operating handle, vertically disposed ears secured to the reinforcing band and having their upper ends bifurcated to form sockets for the reception of the ears, trunnions extending laterally from the reinforcing band, a locking bail pivotally mounted on the trunnions and having a cam face adapted to engage the lugs when the bail is moved to operative position, enlargements formed on the reinforcing band and provided with inclined faces, a slotted arm extended laterally from the reinforcing band, extensions formed on the pivoted ends of the yoke and having their ends inclined for engagement with the inclined faces of the adjacent enlargements, the closed end of the yoke being bent laterally to form a loop adapted to register with the slot in the arm for the reception of a locking device.

In testimony that I claim the foregoing as my own, I have hereto affixedv my signature in the presence of two witnesses.
